The SeaWiFS instrument aboard the Seastar satellite has been collecting ocean data since 1997. By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon. This animation shows an average of 10 years worth of SeaWiFS data. Dark blue represents warmer areas where there tends to be a lack of nutrients, and greens and reds represent cooler nutrient-rich areas which support life. The nutrient-rich areas include coastal regions where cold water rises from the sea floor bringing nutrients along and areas at the mouths of rivers where the rivers have brought nutrients into the ocean from the land. Note: This animation depicts the 10-year average from 1997 to 2007 of SeaWiFS ocean chlorophyll concentration and land Normalized Difference Vegetation Index (NDVI) data on a rotating globe. Data Collected: 08/29/1997 - 10/23/2006. Animator: Alex Kekesi (GST). Scientist: Gene Feldman (NASA/GSFC), Michael Behrenfeld (Oregon State University). Platforms/Sensors/Data Sets: SeaStar/SeaWiFS, SeaStar/SeaWiFS/Sea Surface Temperature.
